I am unsure of native Florida snakes, I live in California. I am unsure if there are any Milksnakes out there, but they are related to the Kingsnakes, which I know Florida does have a lot of different species of Kingsnakes.
Yes, always have the proper tools when you are out snake hunting, the last thing you need is to be in a compromising position without any hooks or tongs. I also use leather gloves, which turned out for the best for me as the last time we went out the little snappy shovel nose we found turned out to be mildly toxic (the last thing I would have wanted is swollen hands) and too small to just be picked up with tongs or pinned with a hook. We catch and release, we are doing a study here in California.
I usually start hunting at dusk and continue until about 1-2am. Long hours but we ususally find at least 8 reptiles a night. Keep you eyes on the road as they will usually be cruising across and sitting on the warm asphalt. Having a driver and a jumper is a good idea as one can jump out as the other pulls the car off the road (also in case of a poisonous bite you will need a ride to the hospital). Take the desert roads that are not traveled often, when you see little sticks that wiggle across the road in your headlights get ready to run, they are fast.

I do hope these will be helpful in your adventures. Good luck and please be safe, remember that some snakes look safe but they may infact be poisonous.
